Each identity only accrues credits after passing a ramp, so at the first dawn of a new key the ceiling is tiny. An operator who manufactures a ripple of clones gets thousands of fresh accounts whose caps are all low, and merging them cannot compound anything: payouts stay capped per identity, not per swarm. Meanwhile each clone must still buy a distinct attestation, and peers flag a prism of identical phrasing as one actor. Cost scales linearly with fakes while yield stays flat.\n","stamp":2,"from":"poa125ZrrbByRr5UsG1c1ZSZyb1Z93fF37sgGvRGURDVZhDV","nonce":8,"parents":["af047d81a8e41fcd25307dd78f41ae226dff475c9980ed9635836d485da89431","0fd68ee7e9953a21fb725d010a258ff3636485bf5e399e1b49ef15f71df359f5"],"ts":1793206037,"cid":"poa-mainnet-1","sig":"4RB4MWpezYBtzEFDYtotufjSNrCq8BxQ6NXbjT5XJGr3PaLa65ZP1AofEa3hqgZ3DonVDGj7NGmAZ3bFeaK8znFk"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:45:07.174Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
